IMPROVEMENT IN POSTMARK ING AND CANCELING MACHINES.

Specification forming part of Letters Patent No. 219,587, dated September 16, 1879 application filed June 21, 1879.

To all whom it may concern:

Be it known that I, THOMAS LEAVITT, of Everett, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Postmarking and Canceling Machines, of which the following,

taken in connection with the accompanying drawings, is a specification.

My invention relates more especially to the ing that end, which will be best understood by reference to the description of the drawings.

Figure l of the drawings isa plan of so much of a machine as is necessary to illustrate my present invention. Fig. 2 is a side elevation of the same; and Fig. 3is a longitudinal section of a portion of the feed-arm.

A A are the side frames of the machine, connected together by suitable tie-rods and the vertically-arranged plate 0, to the back side of which is secured the hopper B, as

shown.

D is the type-cylinder, mounted in fixed bearings in the frames AA 5 and D is the-impression-cylinder, mounted in yielding boxes D which are fbrcedtoward the type-cylinder by the springs to. The cylinders D and D have secured to their shafts the geanwheels b and I), respectively, which mesh into and are rotated by-the two gear-wheels c and a, respectively, the gear-wheels 0 being mounted upon the driving-shaft E, which has mounted thereon the fly or crank wheel E. The shaft of the cylinder Dhas firmly secured to the end thereof opposite to the gear-wheel 1) two cams, F and G, which act, respectively, upon thetrucks d and c, mounted upon pins set in the movable ends of the levers H and I, secured to the rocker-shafts H and I, as shown.

J is a feed-lever, pivoted at one end tothe movable end of the lever K, secured upon the rocker-shaft H, and at or near the middle of its length to the upper end of the crooked link or connecting-rod L, the lower end of which is pivoted to the movable end of thelever M, secured upon the rocker-shaft I, all so arranged that the lever J will have imparted to it an endwise motion toward the hopper, a

downward motion of its inner end, an endwise motion away from the hopper, and an upward motion of its inner end, whereby the toothed feed-plates g g are made to engage with the secured to the lever or pad IL, which is pivoted between the ears i t on the lever J said lever or pad h, with the feed-plates g and g secured thereon, being rendered adjustable to vary the projection of the toothed plates into the hop per by means of the set-screw j and spring k.

The truck (I is held in contact with the cam F by the tension of the spring I, attached at one end to the lever N, secured upon the rockershaft H, and at the other end to some fixed part of the machine, and in like manner the truck 6 is held in contact with the cam G by the tension of the spring m, attached at one end to the lever O, secured upon the rockershaft 1, and at the other end to the frame of the machine.

A slot (not shown) is cut through the plate of letter and cards, and reduce to a minimum the friction upon the letters or cards tending to resist their down ward movement.

The bottom of the hopper B is cut short, so

as to form a throat or opening, 0, between its front end and the plate (J, through which the letters and cards are fed to the cylinders, said throat being closed against the accidental passage of a letter or card by the light springfingers p 19, secured to the inner face of the plate 0 and extending downward and backlever H, trucks d and e, calnsF and G, levers Ward across said throat, as described in an- I and O, connecting-rod L, and the sprlngs Z other application of even date herewith. and m, all arranged and adapted to operate What I claim as new, and desire to secure substantiallyas and for the purposes described.

plates or surfaces at one end, and pivoted at N. G. LOMBARD,

its other end to the lever K, rocker-shaft H, O. H. DODD.
